Secretion of extracellular matrix (ECM) proteins by human adipose‐derived mesenchymal stem cells (MSCs) under different culture conditions. (A) Western blotting analysis of ECM proteins. ECM proteins (collagen I, fibronectin and laminin) produced by 2D cultured MSCs, 3D spheroids of MSCs and 3D spheroids‐derived cells, were analyzed by Western blotting. GAPDH was the internal control. Band intensities were quantified and normalized to the internal control. (B) Statistical analysis of collagen I levels. (C) Statistical analysis of fibronectin levels. (D) Statistical analysis of laminin levels (**P < 0.01).
